How do you solve #-4( 5+ 8n ) - ( 5n - 4) = 1- 3n - 5n#?
1 Answer
First, simplify the equation, then perform the same operations on both sides to isolate
Explanation:
The first thing we should think of is how to simplify the equation. We notice that there are parentheses and multiplications which can be performed on the left-hand-side of the equation. Let's start there and see where we can get. We'll begin by looking at the multiplications outside the parentheses:
Note that the multiplication of the first parenthesis is clearly by a negative value, while the second is not so obvious, so we can make it clear by multiplying by
now we can gather terms of the same type on each side:
adding like terms together we get:
this is as simple as we can get each side. To solve this equation we need to isolate our variable,
Next, we can get rid of the
finally, we can divide each side of the equation by
